I am passing a pair of serialized objects into a vb.net webserviceThe first one maps to a known structure, so I am using the structure type in the parameter list of the webservice. The second object may map to one of 6+ structures.A field in the first object will tell me which structure to use for the second object once both objects are passed to the webservice.
The issue I'm currently having is mapping multiple GUI fields to object properties (i.e. Presentation layer to Business Logic Layer mapping). To be more specific, this is in VB.Net 2.0 WinForms. The nature of the solution requires us to have 4 columns which exhibit the same type of behavior on our GUI - each column consisting of 11 textboxes (we'll just use this small sample size, as the problem extends beyond 11 textboxes).
What I am currently doing is setting the tag of each textbox in all four columns to a value like so:
As you can see this can get very bad, rather quickly. Currently we're setting 43 some odd properties that can be mapped to -- thus that select statement is extremely long -- many of which are embedded in multiple methods to try and attempt DRY (I've watered down the code to essentially a conceptual implementation).
Question is: how can I refactor this? I've attempted using a dictionaries/hashes to a certain extent, but it either became overly complex, or just plain didn't make an implementation sense as it convoluted the problem even more.
I am using asp.net with vb for my scripts.I want to use an array of a Structure to store data parsed from an xml file.[code]All appears to work fine until I add the code that is in bold, I then get the Object reference not set to an instance of an object.
We are busy with a TabControl1 with 5 tabs. On these 5 tabs will be made the exact the same object structure with the same script.What is the best way to organize the TabControl1.

I am using VB.NET to automate a web form submission using SHDocVw.InternetExplorer. I have navigated to the form, filled in all of the fields successfully, and clicked the update button. By design the web application then opens a JavaScript SubModal window in the center of the screen. It looks like a "floating iframe" for lack of a better description. [code]I need to find a reliable way (i.e Not SendKeys). to get the HTML source of this popup in order to click a button.
I keep getting the 'Object Expected' error within my page script when I click the button.I've debugged using fire-bug and the id passed to the JavaScript method is the correct id and document.getElementById(a) finds the button. The error keeps occurring in the _doPostBack. Can this be caused because the button is inside a modal popup in a gridview cell, and the gridview is inside a update panel. The reason I'm still using the JavaScript is the Post-Back event in the GridView.RowCommand did not occur without this.
The code:
function addAcc(a) { var btn = document.getElementById(a); //get the button, not necessary but safer alert(a); //To see the button id
I was wondering if there is a way to take an object in Visual Basic 2010 (Express, FWIW) and browse through its structure to visualize how the data inside is laid out.For example, I have an object called "model" that is populated by a function that is a black box to me. Model is set by a "read" function that loads a DXF file from disk. The read function isn't very well-documented.
What I've discovered is that model.Entities ends up containing a list of different objects, all with different properties. I'd like to be able to simply browse this list of objects and view their associated properties and values at run-time, similar to how you can use Intellisense to view a list simply by typing "blah." and waiting for the pop-up to appear.A tree view that you can pop open and closed would be excellent. Obviously this has to work during run-time rather than in the editor because the file hasn't been loaded if the program isn't running.
Is this something that's possible in Visual Basic 2010? Is it a built-in feature I can't find?
I have a webpage that contains an ActiveX object, called object1, and a javascript function, called alertMe(input). I wish that if user clicks on different location on object1, it will call the javascript function. Is it possible to do this? If it's possible, how should I write the calling in the ActiveX object?
Well I am trying to make a exe that shows a swf game(Club Penguin). When ever I run the exe and login to the swf game, A Internet Explorer Window pops up and its title has some javascript. After a few minutes the window closes and I get an error:Internet Explorer cannot download.Unspecified error.After this the game runs fine, But if I go to a room or something in the game, It does the same as above. (You might need to play Club Penguin in a Visual Basic Program to see what I mean.)
Is there any way of accessing the keys and values (in javascript) in this array without knowing what the keys are?
The reason my json is structured like this is that the webmethod that I'm calling via jquery is returning a dictionary. If it's impossible to work with the above, what do I need to change about the way I'm returning the data?
Here's an outline of my webmethod:
<WebMethod()> _ Public Function Foo(ByVal Input As String) As Dictionary(Of String, String) Dim Results As New Dictionary(Of String, String)
I am getting a javascript error when I attempt to click on my calendar control.
The html code is: <td align="left" style="width:50%;"><asp:Label runat="server" CssClass="TextFontBold" ID="lblStartDate" Text="Start Date:"></asp:Label>
I am generating an Excel file upon a click of a button in an update panel. It is throwing a parsing error.If I keep the button outside the update panel it is working fine. Why isn't it working in the update Panel?
I'm writing a VB app to do stuff with some existing spreadsheets. I'd like to add a "properties" data structure to an Excel object and have two options:
1.
class ExcelPlusPlus Dim properties As HashTable Dim xlobj As Excel.Application End Class
2.
class ExcelPlusPlus Inherits Excel.Application
[code]....
I much prefer solution 2, as ExcelPlusPlus should respond exactly as Excel.Application.However, Visual Studio (2005) errors out on the "Inherits..." line saying "Classes can inherit only from other classes"
Module Module1 Public Structure structure1 Public TRANS() As structure2 End Structure Public Structure structure2 Public X() As Integer End Structure End Module
I'm new to VB 2008 after having spent a long time with VB6, so I apologize if this is a stupid question. But I'd really like to have this straightened out.
Let's say I have a pretty large structure that has lots of properties.
Code:
Now say that I want an internal database with about 10 instances of this structure total, describing, say, 10 different products that a store sells. When these values are loaded from a database, they remain totally static. (However, they can be different each time a program loads)
Now say that I have a class. Each instance of this class is a type of that BaseProduct structure. Meaning, each instance of the class pertains to one of the 10 types of products that the store sells. However, this class has additional properties that pertain specifically to each instance, which are not static.
Code:
Now, the problem here is... If I have 200 different transactions, each one contains an instance of BaseProduct. BaseProduct is HUGE, and is largely redundant (only 10 types possible), so I think it's a little silly to include a whole copy of it with EVERY transaction. However, the Transaction class really needs information regarding the base product it pertains to. Is there a way to, instead of declaring a New BaseProduct in the Transaction class, to simply make one of the properties of the Transaction class a pointer to a BaseProduct variable?
In VB6, I would accomplish this by making a BaseProduct(10) array, and then giving each Transaction an ID number referring to an entry in that array. But in VB 2008, using class structure, this is impossible. I can't define the BaseProduct(10) array outside of a class in a namespace, and if I define it in the actual application's form, then the class loses modularity since it relies on the application that's using it.
I am trying to communicate with an external device and i am trying to send a byte array to the external device via sockets but i am always getting a response the message size is too small so i am not sure what i have done wrong. Between the data type there should be no alignment present and all numbers are represented in little endian format. The char array is not null terminated as mentioned in the protocol specifications.
I have to send data based on a struct that embeds 2 other struct. So here's my vb.net code for the struct used to convert to byte array and the sending part.
Public Structure MESSAGETYPE_OIP_Login Dim Header() As COMMANDHEADER Dim UserName() As PSTRING
I'm having a problem that's driving me crazy; I can't understand how to convert the XML structure into a class structure (that I want to use to hydrate a XML document).
The XML document looks like this:
xml <?xml version="1.0" encoding="utf-8"?> <artists xmlns:opensearch="http://a9.com/-/spec/opensearch/1.1/" xmlns="http://www.spotify.com/ns/music/1">
I wrote a page Page method in my aspx page. in web service method I need to call FindControl method return textbox and get text box value. But my findControl will take MasterPage object to iterate.
see my code
<script type = "text/javascript"> function ShowCurrentDateTime() { $.ajax({
[Code]....
How to pass Master Page object or Page to Page method?. So I can use in Sared method.
Is there any way I can access Textbox value directly in Page method? I need access couple of controls in Page Method.
